WALTEC Maschinen — Industrial Glass Forming Machinery and Lines

Global supply of automated hot-end glass production machinery from WALTEC Maschinen GmbH / WALTEC. Complete turnkey lines including ESERVO servo feeders, GP-series presses, S-series spinning machines, and robotic handling systems from SpareX.

ESERVO Electronic Servo Gob Feeders and Precision Shears

German manufacturer WALTEC Maschinen GmbH engineers fully automated, electronically controlled production lines and servo forming equipment for hollow glass and tableware. Independent drives adjust gob weights on each orifice. Servo shears handle gobs up to 15 kg.

Feeding modes: single, double, and triple gob operation on one feeder head
Gob weights up to 15 kg for soda-lime, opal, and borosilicate compositions
Direct servo plunger kinematics with programmable weight repeatability
Spare shear blades, revolving tubes, refractory plungers, and drive gears

GP-Series Glass Pressing Machines for Tableware and Insulators

WALTEC GP-series presses provide high-precision forming for glassware, toughened insulators, and architectural glass blocks. Integrated ESERVO press cylinders maintain precise stroke control while cutting energy use. Modular rotary tables with 12 to 20 sections allow rapid mold changes.

Rotary table layouts featuring 12, 16, or 20 sections up to 2,900 mm pitch diameter
Accommodates glassware up to 500 mm outer diameter with outputs to 62 tons daily
Tooling compatibility across block molds, hinged molds, and tulip mold systems
Spare plunger rings, pressing tips, cylinder seals, and mold clamping units

S-Series Multi-Station Glass Spinning Machinery with Servo Drives

WALTEC S-series spinning machines combine servo motion with centrifugal forming for tableware, bowls, and technical glass. Platforms S-9, S-18, and S-24 achieve forming speeds up to 90 items per minute. Independent spindle speed profiles enable simultaneous production of up to three article types.

Configurations S-9, S-18, and S-24 delivering production speeds up to 90 pcs/min
Capable of processing article diameters up to 380 mm and weights to 1.5 kg
Separate servo acceleration profiles and digital recipe controls per spindle
Replacement vacuum cups, spindle bearings, servo motors, and air cooling pipes

W-Series Press-Blow Machinery with Direct Servo Station Control

The W-series upgrades press-blow forming through dedicated servo kinematics and digital control. Five direct servo motors per station replace pneumatic actuators, saving up to 5,000,000 Nm³ of air yearly. Automatic temperature regulation delivers uniform container wall thickness.

Scalable architecture from 1 to 24 stations operating at speeds up to 80 cycles/min
Reduces compressed air consumption by up to 5,000,000 Nm³ annually per line
Automatic Temperature Regulation (ATR) across blank molds and pressing plungers
Spare neck rings, blow plungers, bottom mold stations, and servo drives

Thermal Fire-Polishing Machinery for Precision Surface Finishing

WALTEC fire-polishing lines melt mold parting seams and refine rim smoothness through flame exposure. Horizontal, vertical, and radial configurations treat stemware, mugs, and glass covers. Tracking gas-oxygen burners adjust trajectory to match round and non-round shapes.

Horizontal machines configured for tumblers, stemware, and handled glassware
Dual-slide vertical polishers for rectangular, oval, and square technical glass
Tracking premixed gas-oxygen burners with adjustable flame exposure parameters
Replacement burner nozzles, ceramic tips, rotation spindles, and cam tracks

HLE Take-Out Mechanisms, SCARA Robots and Lehr Pushers

WALTEC material handling systems transfer hot glass articles between presses and the annealing lehr. High-speed HLE take-outs achieve up to 240 cycles per minute with optional 180° rotation. Servo pushers guide articles into the lehr using soft-touch speed profiles to prevent marks.

Two-axis HLE take-out mechanisms operating at rates up to 240 cycles per minute
Articulated 4-axis SCARA units and 6-axis robots for heavy and complex geometries
Dual-axis servo lehr pushers featuring programmable soft-touch stroke control
High-temperature graphite suction cups, gripper fingers, timing belts, and bearings

WTRACK Digital Telemetry and Hot-End Process Optimization

The WTRACK software suite gathers real-time machine telemetry and process metrics across hot-end forming lines. Dedicated modules monitor gob weights, glass temperature curves, and mould cycle stability. Direct integration with plant ERP platforms speeds job setups and cuts article defects.

Continuous optical glass temperature monitoring and thermal telemetry via WTRACK
Yield tracking and drop-loss calculations across feeding, forming, and annealing
Digital data export and interface compatibility with plant SAP and IFS platforms
Industrial PLC modules, operator key interfaces, thermocouples, and sensor wiring

Spare Parts Logistics, ESERVO Retrofits and Technical Field Support

Our engineering department organizes scheduled servicing, field diagnostics, and drive modernizations for WALTEC machinery installations worldwide. Experienced engineers convert pneumatic and hydraulic mechanisms into ESERVO drives. Structured parts dispatch keeps plant downtime to a minimum.

Scheduled preventive maintenance and commissioning for presses, spinners, and feeders
Energy-efficient retrofit packages converting pneumatic setups into servo systems
Direct part number cross-referencing and nameplate matching for mechanical wear items
Cylinder rods, servo motors, servo amplifier modules, spur gears, and seal kits

Machinery Configuration and Technical Sizing of WALTEC Equipment

Selecting WALTEC machinery configurations depends on glass composition, daily tonnage requirements, mold geometries, and target cycle speeds. Technical teams calculate section layout, feeder kinematics, and lehr integration parameters.

Whether producing stemware, hollow tableware, toughened insulators, or automotive glass, engineering teams tailor GP-series presses, S-series spinning systems, and W-series press-blow lines alongside digital WTRACK supervision.
